Course Description
Turbulent flow physics,
statistical and spectral analysis, and equations; scales of turbulence;
isotropic turbulence; free shear flows; wall flows (channels, pipes, and
boundary layers); coherent structures; turbulence modeling (RANS, LES, HRLES), and
DNS.
Objective and Approach
Provide a comprehensive and
rigorous treatment of turbulent flow, which is an important topic in modern
fluids engineering, including detailed study of the underlying mathematical physics
principles and modeling for selected topics with wide-ranging
applications. More advanced topics are
introduced. Turbulent flow can be
considered as a terminal course for M.S. students and as a sound foundation for
other advanced courses such as inviscid, viscous, or compressible flows;
combustion theory; interfacial flow and transport processes; multiphase flow
and transport processes; computational fluid dynamics and heat transfer; and
independent and/or M.S. and Ph.D. study research. The subject material is covered
through class lectures, text and other reading, homework problems, midterm and
final exam and class project.
Syllabus, Assignments and
Grading
Syllabus is attached below, and the
class schedule follows the syllabus including dates for lectures, reading and
homework (HW) assignments, class project and exams. Class project consists of independent study
by each student in general area of turbulent flow mathematical physics principles
and modeling, including proposal and class presentation. Final grade is based on HW (100) + class
project (150) + exams (250) = 500 total points.
Exams and point breakdown are shown in the class schedule. Exams are open textbook only.
Project proposal: objective, approach, references,
anticipated results
Project outline: objective, approach, results, conclusions
Grading: technical quality 75%; organization and
presentation 25%
